A one-piece driveshaft over 40" require a larger diameter pipe, in lieu of the smaller diameter, as found in the two-piece driveshaft. While spinning at high speed, the smaller diameter driveshafts will rotate out of axis and begin to wobble and may actually come apart. When going to a longer shaft, the larger diameter shaft will keep the shaft spinning in axis, due to the larger cross section. I believe the new one I had fabricated was over 40" and under 55" and was approximately 4" in diameter. I didn't measure it, so I am not sure of the actual diameter or length.
